Heating Ovens Thermo Scientific Heratherm heating and drying ovens are now available in three different models: general protocol, advanced protocol and advanced protocol seecurity. Each unit is available in 60, 100 and 180 litre sizes with a choice of gravity or mechanical convection. Special insulation and a heat-decoupled door reduce energy consumption and minimize heat transfer to the environment. All models include an easy-to-use user interface, automatic over temperature alarm and data interface. The general protocol ovens are ideal for everyday heating and drying applications, operating up to 250° C. A timer function enables unit operation at defined times to optimize workflow. Where greater flexibility or temperature accuracy is required, the Heratherm Advanced Protocol ovens operate as high as 330° C. An extended timer function offers the choice of weekly, real-time or hour-driven settings for advanced flexibility. The program function can store up to 10 predefined cycles making it easy to undertake processes involving complex temperature ramping and holding steps. Fan speed and damper position can be controlled electronically to facilitate optimal heating, while the unique boost function allows rapid heating and reduces long-term energy consumption. The Heratherm Advanced Protocol Security ovens incorporate an additional under temperature alarm, as well as a lockable door with an alarm, making them ideal for working with precious samples and long-term processes. The auto-dry function shuts the oven down upon completion to maximize energy efficiency, and an optional stainless steel exterior makes it ideal for use in pharmaceutical and clinical laboratories.

Glove Bags The Air Science Purair Flex with film isolator features an innovative curved film design with versatile tapered sleeve and glove options. Unlike other glove bags, the double O-ring design on the standard polyurethane cuffs allow users to quickly and easily change gloves to meet a variety of dexterity needs. Semirigid support rods make the Purair Flex easy to set up and provides increased stability, even if the bag is not inflated to full pressure. Safety options include HEPA filter availability, bag-in or bag-out port, and optional nitrogen purge inlet connections.

Syringes Hamilton Company, introduces the Neuros syringe, specifically designed for the neurosciences. Neuros syringes are available with ultrafine 30, 32 or 33 gauge needles that accurately dispense 50 nL to 100 µL. This enables precision animal brain injections with minimal tissue damage and reduced variability. A unique, adjustable needle sleeve maintains rigidity and ensures a targeted injection path to an exact location. Two needle sleeve options are offered, one with a blind stop for cannulated applications and the other for use with stereotaxic holders, each with adjustable needle exposure of zero to 20 mm.

Light Source Ocean Optics’ Vivo NIR Source is a compact, tungsten halogen light source for VIS-NIR spectroscopy across the 360-2000 nm range. Compatible with all Ocean Optics spectrometers, optical fibers and sampling accessories, Vivo delivers powerful output for reflection and other measurements. The high powered source is ideal for use in NIR analysis of pharmaceuticals, grains and oils, as well as food safety applications. Vivo’s four tungsten halogen sources, arranged for reflection measurements at a 90 degree angle to the detection fiber, can be turned on and off for precision control. The powerful bulb output enables shorter spectrometer integration times than conventional methods-as fast as 1ms with some system setups. An inner cooling fan reduces the risk of overheating the sample to ensure accuracy. The Vivo can be attached to Ocean Optics’ RTL-stage or other standard for stability and control. Powered by an included universal power supply, the Vivo’s tungsten halogen bulbs are rated for 2,000 hours.

Vacuum The T-Station 75 is Edwards’ new entry level turbopumping system. The T-station 75 turbopumping cart is the smallest in Edwards’ range of pumping stations and can pump a chamber to the required vacuum thanks to higher capacity backing pumps. It can be combined with a choice of either an oil sealed E2M1.5 backing pump or an XDD1 diaphragm pump where a totally dry system is desired. The T-Station comes with a TAG (Turbo and Active Gauge) controller fitted as standard which enables single button start/stop of the system.
